.mkv exporting problems

[Selur]

On that encode you used:

# deinterlacing
ConvertToYV12(interlaced=true)
Yadif()
# adjusting frame rate
SalFPS3(60.0)
# cropping
Crop(8,0,-8,0)# 704x576
# filtering
# scaling to 1440x1178
LanczosResize(1440,1178)

so you:

• threw away part of the color info (422->420)
  
• used Yadif and prodced 25fps
  
• used SalFPS3 to go from 25 to 50fps
  
• cropped
  
• resized
  

Correct. So InterFrame is the culprit for reducing the file size despite having more frames? I take it that isn't exactly a bad thing?

That depends. If your output is 4:2:0 than it will occur somewhere along the line so no harm.
If your output should be 4:2:2, throwing away a good protion of the data might not be good thing.
-> Comparing the size of lossless outputs with different color samplings makes no sense.
Comparing the size of lossless outputs and different interpolations without looking at the actual content makes no sense.
